New moms and dads continue to be deprived of sleep a full six years after their children are born, a new study has found.
Researchers tracked the long-term sleep patterns of 2,659 new parents from 2008 to 2015 to judge when, if ever, they returned to their normal sleeping patterns.
Unsurprisingly, sleep deprivation peaked when babies were about 3 months old. Women suffered more sleep loss than men during this period. Breastfeeding babies cost mothers more sleep than formula-fed children.
